“…In addition to the microtome method, freeze-fracture is used as a cross-section processing method for SEM observations of plant samples 48 , 49 . In the freeze-fracture method, the fracture plane tends to pass through the center of lipid bilayers in cell membranes, exposing the extracellular face (EF) and protoplasmic face (PF) 50 .…”

“…The rosette cellulose synthesis complex is observed as six particles in freeze-fracture replicates of the protoplasmic face 51 , 52 . In SEM observations, freeze-fractured samples are generally observed using secondary electrons providing information on the morphology and surface topography 48 , 49 . In contrast, BIB milled samples are suited for imaging with backscattered electrons providing information on material composition and density because the ion etched surfaces are extremely smooth.…”

“…Além disso, folhas sob YT-PC apresentaram menor espessura da cutícula e parede celular na face abaxial em relação ao sistema Y descoberto. Além dos estômatos, N. tropicalis pode penetrar diretamente através da cutícula na face abaxial da folha RASERA).et al, 2019). Cutículas menos espessas podem facilitar a penetração dos patógenos e o processo de infecção (AGRIOS, 2005).…”

“…A germinação ocorre em uma faixa ampla de temperatura (5 a 35 °C), porém os maiores valores de germinação (acima de 50%) são observados entre 15 e 30 °C (ANGELOTTI et al, 2011;RASERA et al 2021). Após a germinação, hifas de infecção são formadas e emitem apressórios, que formam o peg de penetração, os quais penetram através dos estômatos ou através das junções das células epidérmicas, em torno de 12 horas após a inoculação (RASERA et al, 2019). Temperaturas entre 15 a 30°C combinadas com duração de molhamento foliar de 6 horas são necessárias para a infecção por N. tropicalis (ANGELOTTI et al, 2014).…”
